Q:What is the concept of lightweight refractory material?
Lightweight refractory material has high porosity, mechanical strength and erosion resistance. Compared with normal refractory bricks, it is a kind of refractory material with large volume shrinkage in high temperature, low thermal conductivity and small bulk density. It is used as thermal insulation material in industrial furnace and other thermal equipments. It has poor wear resistancel.
Q:I would like to ask a friend that how much is the fire endurance of level A fireproofing glass?
Fireproofing doors can be divided into Class A, Class B and Class C by the fire endurance, the fire endurance is seperately not less than 1.20h, 0.90h and 0.60h. Fireproofing glass is a kind of special glass which can retain its integrity and insulation in the prescribed fire test, it can be divided into three categories according to fire resistance rating: class A is the fireproofing glass with refractory integrity and refractory thermal insulation. Such glass has the properties of transmittance, fireproofing (smoke insulation, fire insulation, heat radiation shielding), sound insulation and shock resistance, which is suitable for architectural steel and wood fire doors, windows, partition walls, daylighting roof, ceiling screen, perspective floor and other building components required both transparent and fireproofing. Class B is a fireproofing glass with refractory integrity and thermal radiation intensity. Such fireproofing glass is mostly composite fireproofing glass with transmittance, fireproofing and smoke insulation. Class C is a fireproofing glass with refractory integrity. Such glass has the features of transmittance, fireproofing, smoke insulation and high strength. it can used in partition wall, fire window and outdoor curtain wall without the thermal insulation requirements. fireproofing glass can be divided into composite fireproofing galss and monolithic fireproofing glass by the structure.
Q:What are the raw materials of refractory concrete ?
Q:How to divided the grade of external wall thermal insulation materials?
Synthesized the three versions of GB8624 (1997,2006,2011), external wall thermal insulation fire rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. There are many technical indicators to make specific division, but I partly cannot report for a while, because it is very professional and technical. I hope I can help you!
Q:How to make the service life of refractory materials longer?
Take acid resistant refractory materials as example: the atmosphere should be acidic atmosphere, if used in an environment whose temperature is 1900℃, it would exacerbate the loss of refractory materials, so don’t use overloaded. Second, select the appropriate refractory materials according to the environment. For example, if its operating temperature is 1800℃, generally speaking, the normal use of it according to the instruction of refractory materials would be fine.
Q:What are the types of advanced refractory?
it can be divided into two categories of general and special refractories ordinary refractories by chemical properties into acidic, neutral and alkaline. Special refractory composition divided by high temperature oxide, refractory compounds and high-temperature composite materials Furthermore, according to refractoriness can be divided into ordinary refractory products (1580 ~ 1770 ℃), advanced refractory products (1770 ~ 2000 ℃) and grade refractory products (2000 ℃ above). the article can be divided into blocks (standard bricks, shaped bricks, etc. ), special shape (crucible, sagger, pipe, etc.), fibrous (aluminosilicate, zirconia and boron quality, etc.) and a random shape (refractory clay, pouring materials and ramming mixes, etc.) according to the sintering process it can be divided into sintered products, cast products, melt blown products.
Q:whether the fire resistant level of aerated concrete building blocks can reach the grade one?
Aerated concrete building blocks is made by calcareous materials (such as cement, lime) and siliceous material (such as sand, fly ash, slag), adding aluminum powder ingredients as filling agent, by mixing with water, casting molding, gas - expansion, raising the pre-cut, and then the high-pressure steam curing of silicate building blocks. when aerated concrete is at the temperatures below 600 ℃, the compressive strength will be increased slightly, when the temperature is at about 600 ℃, the compressive strength is close to the compressive strength at normal temperature, so the aerated concrete, as building materials, the fire performance can meet the national fireproffing safety standards level.
Q:What are the main components of refractory cement?
Refractory cement, also known as aluminate cement, can also be gray. Aluminate cement is often yellow or brown. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. The main mineral of aluminate cement is mono calcium aluminate (CaO · Al2O3, abbreviated CA) and other aluminates, and a small amount of dicalcium silicate (2CaO · SiO2), etc.
Q:Who knows what is the standard of insulation material whose fire proof is level A?
Non combustible materials of level A: WW inorganic active wall thermal insulation material, Cement foaming thermal insulation board, Glazed hollow bead insulation mortar, rock wool board, Glass wool board, Foam ceramic.Non combustible materials of level A, endowed with low density, low thermal conductivity, higher bearing capacity, convenient construction , economy and durability, are widely used in heat pipe, heat equipment, other industrial pipeline equipment , thermal insulating materials on industrial buildings, and used as heat preservation, thermal insulation, sound absorption materials of industrial and civic buildings.Non combustible materials of level A are used more for refractory protection coating material of steel structure because of its good thermal stability.
Q:What are unshaped fire-resisitance materials?
Refractory castable, refractory plastic material, usually classified according to construction and manufacture method, unfired bricks precast block, refractory pressed into material, refractory cast material, refractory coating, refractory ramming material there are many classification methods
